1. TEST PATTERN

Use the test pattern to check the image quality. The circles should be complete and round, the lines in the frequency patterns should be clear and defined, and the color gradients should not have any breaks or banding.

2. DEFECTIVE PIXELS ON BLACK

Check if there are any defective pixels on the monitor.
All of the pixels should be black. If you see a pixel illuminated in color, this indicates a continuously illuminated subpixel.

3. DEFECTIVE PIXELS ON WHITE

Check if there are any defective pixels on the monitor.
All of the pixels should be white. If you see a black pixel, this indicates a missing pixel.

4. DEFECTIVE PIXELS ON RED

Check if there are any defective pixels on the monitor.
All of the pixels should be red. If you see a black pixel, this indicates a missing red subpixel.

5. DEFECTIVE PIXELS ON GREEN

Check if there are any defective pixels on the monitor.
All of the pixels should be green. If you see a black pixel, this indicates a missing green subpixel.

6. DEFECTIVE PIXELS ON BLUE

Check if there are any defective pixels on the monitor.
All of the pixels should be blue. If you see a black pixel, this indicates a missing blue subpixel.

7. UNIFORMITY

Assess the uniformity of the image using various grayscales. The brightness should be equally distributed across the entire image, and the image shouldn’t have any colorful areas.

Gray Tone

8. COLOR DISTANCES

Check the extent to which your monitor can display similar colors while keeping them differentiable. You can create two color patches to do so. The more similar the two colors that can still be differentiated from one another are, the better your monitor can differentiate between the colors. This test is also well suited for making a direct visual comparison between two different monitors.

9. GRADIENTS

Choose a greater viewing distance to check the display of gradients. The grayscale image should be reproduced in the overall view without any unnecessary color and with an even gradient, and, at 256 intervals, there should not be any noticeable abrupt changes in brightness between individual grayscales. At a smaller number of intervals, the respective bars should be clearly differentiable from one another.

10. SHARPNESS

This test allows you to determine whether your monitor can reproduce text sharply and without any shadows, independently of other influences, such as text smoothing.

11. VIEWING ANGLE

Test the monitor’s viewing angle stability. When you increase the viewing angle, the size and shape of the circles displayed should remain almost the same. Slight changes may appear. Less is better.

12. GAMMA

Determine your monitor’s gamma value. Use the slide bar to change the logo’s grayscale until the logo blends into the background to the greatest possible extent. The value shown corresponds to your monitor’s gamma value.

13. RESPONSE TIME

This test primarily serves to compare the response times of two monitors. Start by selecting a speed that creates clear streaks on the rectangles. However, you should still be able to clearly follow the rectangles visually. Then vary the distance between the rectangles until the lower edge (streak) of the one on the right no longer overlaps the lower edge of the one on the left. The smaller the distance, the shorter the response time. When comparing several monitors, select the same speed.
You can also use this test to recognize the effects of your monitor’s various setting options, such as overdrive, refresh rates and blur reduction.
